cH Rl'Lns J. COOPER, ,ORMOLINE, ILLINOIS, Ass GNoR on ON -HALF To H. w. COOPER sAnnLERY HARDWARE MFG. COMPANY, OFivIOLIn ILLINOIS, A CORPORATION f O ILLINOIS.

To all whom it may concern: Be it known that I, CHARLES J. COOPER, a citizen of the United States, residing at Mo line, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Chain-Cockeyes, of which the following is a specification.

My invention relates to improvements in chain cock-eyes such as are used in connection with harness, and the object of the 111- vention is to provide a cock-eye so constructed as to prevent displacement of the chain or links, thereby obviating damage to the leather or other parts of the harness, while at the same time the construction is such as to allow of the insertion or removal of the chain link engaging the eye of the cock-eye.

The cook-eyes which have heretofore been brought to my attention are of two kinds: First, those in Which the eye of the cock-eye permits free play of the chain link, which results in damage to the leather of the trace, by reason of the end link of the chain striking against the leather loop surrounding the shackle of the cockeye; and second, that type of cock-eye in which the eye is completely closed. In the latter type, the closed eye prevents damage to the leather, but it is impossible to detach the link from the cockeye when it is desired to use a chain of different length or repair an old chain.

My invention is designed to embody all of the advantages of the other types of cock-eye and to be subject to none of the disadvantages of either type.

A specific embodiment of my invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation of a chain cockeye constructed according to my invention, together with the parts associated therewith;

Fig. 2 is a section taken on the line 22 of Fig. 1;

Fig. 3 is a perspective view of the principal part of the cock-eye; and

Fig. 4 is a modified form of pin for the cock-eye.

Referring to the drawings, 10, represents the end of the leather trace which, as is usual, is looped around the metal sleeve 11 which surrounds the cock-eye pin or bolt 12. The said pin orbolt 12, as illustrated OHAIN- OKEYE. A

chain 16, the other end of the said chain being engaged with a suitable hook on the whiflie tree. The end link 17 of said chain is passed through the eye 18 situated at and forming a part of the junction of the ends of the limbs 13 and 14 of the cock-eye.

The eye 18 is large enough to permit the proper amount of play or movement of the end of the link 17, but, as shown, the open ends 19 and 20 of the eye are brought together, as shown in Fig. 1 at 21, the distance across the gap 21 being small enough to prevent the end of the. link 17 from passing out of the eye 18 of the cock-eye. Hence it will be seen that there is no possibility of in its length, the link 17 is reduced in crosssection by flattening or otherwise, as indicated at 22 in Fig.2. Such flattening allows the link 17 to be manipulated in an obvious manner so that it may pass out through the narrow gap 21 at the open end of the eye 18 of the cock-eye.

The described construction effects a substantial saving in metal over those types of prior constructions hereinbefore referred to.

Fig. 4 illustrates a shackle pin in the form of a square-head bolt and nut which may be used, if desired, in place of the flat-head pin 12 illustrated in Figs. 1 and 2.

The scope of the invention should be determined by reference to the appended claims.

I claim' 1. In combination, a chain cock-eye comprising a pair of separated limbs connected at one end to form an open-ended eye, the opening to which is of substantially less width than the interior width of the eye, a removable member connecting the opposite ends of said limbs, and a chain link having an. endless metallic band having one of its ends engaged in said'ey'e with a'loose fit therein, the opening to said eye being of less it may be disengaged from said eye.

2. In combination, achain having an end link of conventional oval shape, constructed of metal of. circular cross-section, one side of said link havingthegmetal thereof reduced'in thickness, a chain cock-eye comprising a pair of separatedlimbs' connected integrally at one of their ends to form a partially closed eye in-Which said link is engaged, the opening to which is of less Width than the diameter of the metal comprising the link but of greater Width than the thickness of the reduced portion of said link, and a removable pin extending between and connecting together the opposite ends of the cock-eye.
